  • Publication number: 20150347798
    Abstract: A workstation processes a product by imaging an indicium associated with the product in a transaction, and images a sheet-like target associated with the transaction. A window is supported in a window plane in contact with the target during target imaging. An imaging assembly captures light from the indicia during product processing, and from the target during target imaging, over a plurality of fields of view extending along different directions through the window. Each field bounds an area in the window plane that is smaller than the entire target. At least one pair of the fields partially overlaps each other in the window plane. The fields overlap contiguous portions of the target during target imaging. The light from the contiguous portions is captured by the imaging assembly as a plurality of target images. A controller compiles the target images into a single output image indicative of the target.

  • Patent number: 9038903
    Abstract: A method includes transmitting from at least one of the imaging sensors to a controller a short frame data that is collected by the at least one of the imaging sensors when the illumination source is activated to provide the illumination light toward the target object with a first illumination level. The method further includes transmitting subsequently from the at least one of the imaging sensors to the controller a regular frame data that is collected by the at least one of the imaging sensors when the illumination source is activated to provide the illumination light toward the target object with a second illumination level that is determined based upon the short frame data. The size of the regular frame data being at least 50 times larger than the size of the short frame data.

  • Patent number: 9010643
    Abstract: An imaging system for electro-optically reading a symbol located within a range of working distances from the system, utilizes a solid-state imager for capturing return light from the symbol and for generating an electrical signal indicative of the captured return light, and a controller for decoding the electrical signal into data indicative of the symbol A memory stores a known set of values for a plurality of optical characteristics of the symbol, such as size and contrast characteristics of the symbol when the symbol lies in a restricted zone within the range of working distances. The controller is operative, after the symbol has been successfully decoded, for processing the size and contrast characteristics of the decoded symbol, and for determining that the decoded symbol has been successfully read within the restricted zone when each size and contrast characteristic lies within the known set of values stored by the memory.

  • Patent number: 8840025
    Abstract: An arrangement for, and a method of, preventing a misread of a one-dimensional symbol that can be read in either one of two polarities in an electro-optical reader. A data capture assembly captures light from the symbol, and generates an electrical signal indicative of the captured light. A controller simultaneously processes and decodes the electrical signal as a first decoded result of one of the polarities and as a second decoded result of the other of the polarities. The controller also determines the validity of the first and second decoded results, and generates an output in dependence upon the validity determination.

  • Patent number: 8690063
    Abstract: An apparatus and method electro-optically read indicia, such as a direct part marking (DPM) code, that is raised or sunken relative to a target surface on a target. A solid-state, distance imaging sensor captures a target image comprised of a first set of pixels having first distance values that correspond to a first distance of the code from the sensor, and a second set of pixels having second distance values that correspond to a second distance of the target surface from the sensor. A controller reads the indicia by distinguishing between the first set of pixels and the second set of pixels within the image, by determining abrupt changes in the distance values among neighboring pixels.

  • Patent number: 8528820
    Abstract: A barcode reader for verifying a barcode is attached to an appropriate object particularly suitable for use at a point of sale. A database of expected object signatures in a vicinity of a properly affixed barcode properly is maintained. At a point of sale, the barcode reader obtains an image of a presented barcode (possibly not the correct barcode) and at least a portion of an object to which the presented barcode is affixed. Using data encoded on the presented barcode, the database is accessed to provide an expected signature of the object in the region of the presented barcode. A comparison is made between the expected signature of the object and a sensed signature derived from the image of the object. An improper barcode can thus possibly be identified and further investigation initiated.

  • Publication number: 20130026235
    Abstract: A method of operating a laser scanner for reading a barcode. The laser scanner is configured to operate in at least two operating modes including a scanning mode and an aiming mode. The method includes operating the laser scanner in the scanning mode after a trigger signal is generated by a trigger on the laser scanner, and decoding the electrical signal that is received from the photodetector when the laser scanner is in the scanning mode. If the electrical signal from the photodetector is not successfully decoded after a first predetermined time period since the trigger signal is generated, alternating the laser scanner between the aiming mode and the scanning mode.
